Scientific Linux Security Update : openchange on SL6.x i386/x86_64

Critical Nessus Plugin ID 65013


The remote Scientific Linux host is missing one or more security updates.


A flaw was found in the Samba suite's Perl-based DCE/RPC IDL (PIDL) compiler. As OpenChange uses code generated by PIDL, this could have resulted in buffer overflows in the way OpenChange handles RPC calls.
With this update, the code has been generated with an updated version of PIDL to correct this issue. (CVE-2012-1182)

The openchange packages have been upgraded to upstream version 1.0, which provides a number of bug fixes and enhancements over the previous version, including support for the rebased samba4 packages and several API changes.

This update also fixes the following bugs :

- When the user tried to modify a meeting with one required attendee and himself as the organizer, a segmentation fault occurred in the memcpy() function.
Consequently, the evolution-data-server application terminated unexpectedly with a segmentation fault. This bug has been fixed and evolution- data-server no longer crashes in the described scenario.

- Prior to this update, OpenChange 1.0 was unable to send messages with a large message body or with extensive attachment. This was caused by minor issues in OpenChange's exchange.idl definitions. This bug has been fixed and OpenChange now sends extensive messages without complications.


Update the affected packages.
